Peak Diode Recovery dV/dt Test Circuit
+ Circuit layout considerations
D.U.T.
• Low stray inductance • Ground plane • Low leakage inductance current transformer - + - + - Rg • dV/dt controlled by R + g • Driver same type as D.U.T. V - DD • ISD controlled by duty factor “D” • D.U.T. - device under test Driver gate drive Period P.W. D = P.W. Period V = 10 Va GS D.U.T. l waveform SD Reverse recovery Body diode forward current current dI/dt D.U.T. V waveform DS Diode recovery dV/dt VDD Re-applied voltage Body diode forward drop Inductor current Ripple ≤ 5 % ISD
Note
a. V = 5 V for logic level devices GS
